Vscreen doors, which will he sel.i`latolring,i

when the door is closed and will hold it against accidental unlatching,but will he adapted 'tor disengagement when pressure is applied to thedoor7 and to combine therewith novel means, whereby the door may hereadily looked.

The present invention is distinguished from those combined latches andlocks heretofore known in that it is so constructed that theipartsthereof are reversible and do not require previous calculation as 'totheir enact position; further, in the particular 4construction oit' theparts; still 4lui-ther in the improvedmanner in which the parts are Vthe loi adapted to cooperate with each other.

` The invention is also distinguished trom earlier devices in that theparts are made,

respectively, in one piece, thus greatly sim-- plifyinn,r andcheapening, well as strengthening, them.

'llie embodiment of tho invention hereinafter described and which isshown in thc accompanying drawings in snsceptihle of changes in etail'without departing,l from the spirit and scope of the improvement.

:lin the accompanying; drawingsz-w-llignre ll 'is a perspective showingthe invention in use, tho parts being locked; lig. 2, a view showing,rthe parts in position for encargo ment; Fig. 3, a section through thecom plete latchy and look; Fig. fl, a side elevation of the keeper; andFin'. 5, a, laittmn vii-iw thereof.

The comhined latch and lot-lc con three iarts, the catch l, the koepel'.t

iking member The catch l may be .made 'from a single piece ot' metal,bent or cast, having; the hase d, the substantially cylindrical head oar-A ranged transversely of the base, and the neck 6 which has thentches or recesses 7 is ol? and device to a door ri in its oppositeedges, said notches` or recesses being similar. The neck may also beprovided with rahbetod parts 8 to accommodate the thicknesi'i ol thehase ol the keeper. The hasehas suitable openings for the reception ot'screws and it is intended to he attached to the door, but thearrangement of the `parts may he reversed.

The keeper has a hase 9 provided with openings for the passage of screwsor other fastenings to connect it to the door frame or .jamh and it isformed integral, hy casting or bending, with a flange l0 having,r lips.1.1 disposed inwardly over the base and separated therefrom at lil inorder that they may have a certain degree of springiness or resiliencyto carry out their 'function ol cng'aiging the cylindrical head 5i. rlhefaces 13 are beveled or rounded so that the cylindrical head 5 willlheguided into the space between the termini ot' said lips. After the headhas snappodpast the termini of the lips, it is securely held, as shownin Fig. 1,'

but the door can be readily opened by the application oi pressure, asthe rounded or cylindrical construction oli the head 5 pernrits it to hereadily withdrawn lfromhetween said lips. The engagement oi the lipswith the head, however, latches the door against any aceidinltalopening. t

The base o't the keeper is provided with a hearing' 1 4 lor a locking'loop or hail l5 which is adapted to be swung' over and cn- ;{agcd withthe uppermost notch T' \vhen over it is desired to lock the door. At alltimes the .looking hail is thrown hack and ont of the Way. its hingedengagement with the bearing 1l. is suoli that the latch is frictionallyheld wherever positioned so that it `will not acazidentnlly he jarredinto elmaa'gement with the head ol the catch.

`loth the keeper and the catch can he used either right or illol't, thusadapting` the arardlcss of the direction in which it opens. 'lhelrnovision o'l the` notcllos l on hoth sides of the neck of the `lah-.hinsures one otl said notches heilig in poi-:ition for engggancmenl hythe looking hail,

L 'ardless ot' tho ymsition of the parts.

il'a'vingg thus described my ii'ivontion, what l claim as new and desireto seran-e hy liettcrs llatent, iss

l. A combined latch and lock having. in combination, a catch consistingoi a hase, a neck having notches on opposite sides, and a head, a keeperhaving lips adapted to engage said head, and a swinging,r lockmountoutermost of the notches aforesaid.

2. A combined latch and lock having, in i combination, a, one-piece-reversible catch 4composed of a base, a neck having notches -onopposite sides, and a rounded head, a

keeper having a one-piece4 base, a, flange, and springy co-nvergin lips,and e locking loop or bail hinged to t e base of the keeper and ed onthe keeper and adapted to -engage the adapted to engage Whichever ofvseid notches 10 aforesaid is outermost.
